Edit item with picture in Rails admin 3.1.2 raise an error ' undefined method `url' '

Question

I am doing my ruby upgrade from ruby 2.7.3 to 3.2.2. Beside many other issues I handled alone. I am getting this one with Rails_Admin and edit object with image attached.

App is Rails 6.1.7 version and I am using shrine gem for image uploading 3.4. I have model event and creating event is okay but editing produce an error. When I try to open edit page I am getting:

Showing /home/zire/.rbenv/versions/3.2.2/lib/ruby/gems/3.2.0/gems/rails_admin-3.1.2/app/views/rails_admin/main/_form_file_upload.html.erb where line #6 raised:

on the line:

thumb && bindings[:object].public_send(:"#{name}", thumb).try(:url) || value.url

Answer 1

After lot of try I managed to fix the issue by updating that line to:

thumb && bindings[:object].public_send(:"#{name}", thumb).try(:url) || value[value.keys.first].url

Definitely I think it need more attention and the issue is on the left side of || but for my case this is enough.
